[texts]Ionospheric Plasma Disturbances And Effects On Radio Waves - Lee, Min-Chang
Ionospheric Plasma Disturbances And Effects On Radio Waves by Lee, Min-Chang. "Ionospheric plasma heating experiments were conducted at Arecibo to investigate generation of ionospheric plasma bubbles, sheet-like ionospheric irregularities, Langmuir waves, upper hybrid waves, and ion Bernstein waves. This research has shed light on physics and effects of HF waves on naturally occurring ionospheric plasma turbulence." Digitized by The Defense Technical Information Center (DTIC).

[texts]Radio Wave Propagation In The Presence Of A Tropospheric Duct - Dresp, M. R.
"A full-wave solution has been obtained for radio wave propagation in the presence of an elevated tropospheric layer. This analysis was performed as part of the CNI (Communication, Navigation, Identification) experimental program. The tropospheric layer is modeled as a trilinear refractive index profile with a sufficient lapse rate so as to result in an elevated duct. The analytical solutions give the received signal level for air-to-air propagation paths at UHF, the corresponding signal fading ...

[movies]Nuclear Weapon Effects on the Ionosphere
President Kennedy directed that a series of high altitude nuclear explosions be conducted with the objectives of testing the weapons and determining their effects on radar and communication systems. SRI planned and fielded the measurement system and successfully monitored the radio propagation conditions across the vast area of the Pacific for each test. This movie describes the results
